Simon Diepold discovered that U-Boot incorrectly handled certain DHCP responses. An attacker on the local network could possibly use this issue to obtain sensitive memory contents. ( CVE-2024-42040 ) It was discovered that U-Boot incorrectly handled symlink size calculations in squashfs file systems. An attacker could use this issue with a specially crafted squashfs file system to cause U-Boot to crash, resulting in a denial of service, or execute arbitrary code. ( CVE-2024-57254 ) It was discovered that U-Boot incorrectly handled inode size calculations in squashfs file systems. An attacker could use this issue with a specially crafted squashfs file system to cause U-Boot to crash, resulting in a denial of service, or execute arbitrary code.

In general, a standard system update will make all the necessary changes.
The problem can be corrected by updating your system to the following package versions:
Ubuntu Pro provides ten-year security coverage to 25,000+ packages in Main and Universe repositories, and it is free for up to five machines.
